It said: "While every collision is regrettable, it is encouraging that the proportion of cycling collisions on TfL roads that result in fatal or serious injuries has declined since 2008, indicating that the severity of collisions is falling.

"So far, during 2011 there have tragically been 14 cycling fatalities on the capital's roads, seven of which involved HGVs or tipper trucks. A huge range of practical measures are being delivered by the Mayor and TfL to tackle the issue and make the city's streets safer for cyclists."

Since 2010, TfL has been working to deliver its Cycle Safety Action Plan (CSAP).

It identified 52 targeted actions which the mayor, TfL and other stakeholders need to take to reduce the number of cyclists being killed and seriously injured on London's roads.
